Title: Method and device for producing conductive thin film-coated optical fiber
Inventor: YOSHIMURA ICHIRO
IPC: G01B7/12
Filed: 1990-07-05
Abstract: ABSTRACT OF THE DISCLOSURE   This invention provides a method and a device for producing an optical fiber which make it possible to measure the film characteristics of the inorganic thin films continuously and electromagnetically in non-contact therewith.  Firstly, an optical fiber drawn from a preform is coated with a conductive thin film.  Secondly, the optical fiber is passed through a high-frequency magnetic field to measure an eddy current generated in the conductive thin film in non-contact therewith so as to measure the film characteristics of the conductive thin film.  The device for producing an optical fiber used for this invention comprises a fiber drawing furnace to draw an optical fiber, thin film coating device, and film characteristics measuring device.  The film characteristics measuring means measure the film characteristics of the conductive thin film, based on a variation of an alternating current impedance of the detection coil generated when the optical fiber is passed through the hollow interior of the detection coil.

Abstract: A bi-directional snap-action register mechanism for an odometer-type mechanical register display. The mechanism includes at least one register display wheel and a bi-directional cam mounted coaxially along a common shaft with the register display wheel. The bi-directional cam engages a helical groove formed along the shaft to allow lateral displacement of the bi-directional cam in a direction parallel to a rotational axis of the shaft. A pin is biased by a spring into contact with the bi-directional cam. Rotation of the shaft causes the bi-directional cam to be moved with respect to the pin. The cam abruptly rotates through a predetermined angular distance when the point of contact of the biased pin with the cam moved from a smooth portion to a step transition portion of the cam. The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.

Inventor: HUBE RANDALL R
IPC: H04N1/23
Filed: 1991-08-08
Abstract: In a printer system which allows printing in multiple fonts, where the font to be used is specified in an encoded document to be printed, an operator designation of font equivalency is provided which specifies acceptable font substitutes of available fonts for unavailable fonts. Upon detection of a document specification of an unavailable font, a print controller searches a mapping of known fonts to available fonts to determine if an equivalent font has been designated. The mapping is operator-set in accordance with the operator perception of equivalence. Font equivalency mapping may be a yes/no equivalent, indicating substitution or job fault, or the mapping may have a multilevel substitution hierarchy, in which degrees of equivalency are determined by the operator, and result in different warnings or machine operations dependent on different degrees of equivalency. An operator may also program the job to allow printing if the equivalency falls within a certain degree, changing that degree depending upon customer sensitivity to font use.

Abstract: Abstract of the Disclosure A light absorbing layer, and a window layer formed thereon constitutes a first conduction-type semiconductor layer.  In a part of this first conduction-type semiconductor layer there is provided a second conduction-type region extending to the light absorbing layer through the window layer.  A part of the window layer around the second conduction region is selectively removed.  Consequently even when light intended to enter a light detecting region is incident outside of the light detecting region, most of the carriers generated there are recombined at a surface level of the light absorbing layer before diffusing in a depletion laser.  Resultantly this light detecting device does not  substantially detection sensitivity to light incident outside the light detecting region.

Title: Efficient thermal cycling mold
Inventor: BEARD DOUG
IPC: B29L31/54
Filed: 1991-12-31
Abstract: ABSTRACT OF THE DISCLOSURE A mold for golf balls employs a plurality of cores formed in a body of metal to admit heat-exchange fluid adjacent a molding surface. The small thickness of metal between the cores and the molding surface accelerates heating and cooling of the molding surface, even thought the temperature of the body of the mold is not greatly changed during a molding cycle. In one embodiment, a carrier plate supports a plurality of columnar molds. One or more heat-exchange fluid flow channels carries heat-exchange fluid to the vicinity of the columnar molds. Inlet and outlet cores in the columnar molds permit the heat-exchange fluid to flow from, and return to, the fluid flow channels. In a further embodiment of the invention, heat-exchange fluid flows coaxially into, and out of, the cores to deliver the heat-exchange fluid almost directly to the ends of the cores where they are nearest the molding surface. An insulating tube may be used to reduce heat flow to the mold body.

Title: Normalizing analyzer systems to a standard analyzer

IPC: G01N37/00
Filed: 1992-02-11
Abstract: NORMALIZING ANALYZER SYSTEMS    TO A STANDARD ANALYZER      Abstract of the Disclosure There is described a method of calibrating an analyzer in the field, using parameters designed for a "standard" analyzer that may be different from the field analyzer.  In this way, it is not necessary to use only certain slide elements of a given chemistry on one analyzer, and certain other slide elements of that same chemistry on another analyzer. Instead, the slide elements are made interchangeable by calibration math which allow the field analyzer to convert its raw response RF into a response Rstandard of the selected "standard" analyzer, using the equation (1) Rstandard = B0 + B1 ? RF +  B2 ? (RF)k . The coefficients of this equation are established by comparing, at at least 1 different level of response, RF against Rstandard, optionally using an intermediate spline function gF(RF) in place of RF.
